I'm not talking about the documentation for sys.exit() I'm talking about the documentation for Py_Main(int argc, char **argv)
http://docs.python.org/c-api/veryhigh.html?highlight=py_main#Py_Main This C function never returns anything whether in the interpreter I type "exit(123)" or "sys.exit(123)". I cannot call any of my C cleanup code because of this.
